PURPOSE:To obtain the title Al-Li mother alloy without any breakage and crack by electrolyzing the mixed fuse salt of LiCl and KCl with a hollow cylindrical solid Al as the cathode at specific current density without floating the deposited Li on the bath surface. CONSTITUTION:The mixed fused salt of LiCl and KCl is charged in an electrolytic cell. The hollow cylindrical solid Al as the cathode is dipped in the fused salt, and electrolysis is carried out at 0.005-1A/cm<2> cathode current density to form an Al-Li alloy on the cathode. The deposited Li is not floated on the bath surface by this method, and Na, K, and Ca are also not deposited, and a high-purity Al-Li alloy is formed on the Al cathode.
